Description

Technical Field

[0001] This utility model belongs to the technical field of concrete pile end plates, specifically relating to an integrated concrete pile end plate. Background Technology

[0002] The skirt plate on the concrete pile end plate, also known as the end plate flange or end plate clamp, connects to the end plate and prevents cement grout from seeping out from the end plate and joint, ensuring the integrity of the pile core concrete. In corrosive soils or high-water environments, the skirt plate reduces the intrusion of moisture and chemicals into the connection between the end plate and the pile body, delaying corrosion. Additionally, the skirt plate acts as a protective covering for the concrete; this extended structure helps distribute the pile top load more evenly across the end plate and pile body, preventing localized stress concentration that could lead to concrete cracking during pile driving or pressing.

[0003] Currently, skirt panels are mainly connected to end plates by welding or riveting. The industry is now shifting from manual welding to automated connection. For example, Chinese invention patent CN112404277A discloses a riveting device for pressing skirt panels onto end plates, which simplifies the feeding process of end plates and skirt panels and enables rapid positioning of end plates and skirt panels, improving the efficiency of riveting. Chinese utility model patent CN209078082U discloses an automatic welding device for square pile flanges, which adjusts the position of the welding gun through a welding gun moving device, enabling it to automatically adapt to the welding of square pile flanges of different sizes and specifications, overcoming the low efficiency problem of manual electric welding.

[0004] However, the above processing requires additional steps and labor. Poor welding quality or gaps in the riveting may affect the sealing performance, leading to leakage or structural loosening, especially in applications involving pressure or liquid media. Utility Model Content

[0005] To address the aforementioned shortcomings of existing technologies, this invention aims to solve the problem that precast concrete pile end plates require welding or riveting of skirt plates, increasing processing time and costs. Furthermore, the resulting structural integrity is insufficient, making them susceptible to damage due to processing quality issues or heavy loads, thus affecting grout sealing and encapsulation effects. The purpose of this invention is to provide an integrated concrete pile end plate, where the skirt plate and end plate body are integrally formed, reducing processes, lowering production costs, improving structural strength and rigidity, and simultaneously enhancing sealing performance.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an integrated concrete pile end plate, comprising:

[0007] The plate body, which may be polygonal, irregularly shaped, or circular, may or may not have a central hole.

[0008] The skirt is located at the outer edge of the bottom surface of the board. The outer side of the skirt is flush with the outer side of the board and of equal length. The cross-section of the inner side of the skirt is a beveled or arc-shaped structure. The skirt is larger at the top and smaller at the bottom. The upper part is integrated with the bottom surface of the board, and the lower part is a sharp corner or a short side.

[0009] According to another embodiment of the present invention or any of the foregoing embodiments, the concrete pile end plate is wherein the skirt is formed by continuous casting and rolling, and then hot-rolled in a mold.

[0010] According to another embodiment of the present invention or any of the foregoing embodiments, the concrete pile end plate is wherein the skirt is formed by stamping.

[0011] According to another embodiment of the present invention or any of the foregoing embodiments, the upper part of the inner side of the skirt and the bottom surface of the end plate are connected by a rounded corner.

[0012] According to another embodiment of the present invention or any of the foregoing embodiments, the concrete pile end plate has protrusions in the tension hole and the countersinking hole of the plate, and the protrusions are formed by stamping.

[0013] The beneficial effects of this utility model are:

[0014] 1. The integrated concrete pile end plate of this utility model reduces the extra steps and labor required by traditional welding and riveting processes. The integrated skirt can be directly formed by stamping, continuous casting and rolling or other integrated forming methods. The skirt processing accuracy is higher, the production speed is improved, and it is especially suitable for mass production.

[0015] 2. The integrated concrete pile end plate of this utility model eliminates the joints of welding or riveting, avoids stress concentration at the connection, improves the overall strength and rigidity, and has better grouting and covering effects. Attached Figure Description
